20 Claims.

This invention relates to windows and more particularly to a closure assembly for a Ventilating area.

An object o-f lthis invention is to provide a closure adaptable for field assembly.

Another object of' this invention is to provide a closure assembly that may be attached to the fixed portion of the window in any selected location without alterations.

Another object of this invention is to provide a window assembly that is cheap, efficient, easily manufactured and readily assembled, but at the same time dependable and durable.

Another object of this invention is to provide an interlocking arrangement between the frame bounding the Ventilating area and the closure frame.

Another object of this invention is to provide an interlocking arrangement between the sill extending along the bottom of the ventilatingarea and the closure frame.

Another object of this invention is to provide weather tightness of a field closure assembly against the fixed frame portion.

Other objects and advantages reside in the construction of parts, the combination thereof and the mode of operation, as will become more apparent from the following description.

In the drawings, Fig. ldiscloses a cross sec'- tional view of the window and the closure assembly fo-r the Ventilating area.

Fig. 2 is a partially exploded view of the closure assembly in readiness to be inserted in position upon the fixed portion of the window, which portion is shown in section.

Fig. 3 is a sectional view taken substantially on the line 3--3 of Fig. l.

Fig, 4 is a sectional view of a' modification.

Fig. 5 is a fragmentary cross sectional View of another modification.

Fig. 6 is a perspective view of a taining member.

Fig. 3 has been oriented through an angle of 90, as it was not convenient to show this figure transversely across the sheet of drawings.

In the past it has been the common practice when erecting a building using metallic windows to glaze the window after the completion of the outside walls. This proves advantageous in that the hazard of breaking the window panes when erecting the walls is eliminated. The glazing however, proves to be a very expensive roperation when it is done after the erection of the outside walls. Up to the present time no other method closure re- (Cl. 18S-64) has been developed, as far as known, of glazing the fixed portions of the window. Y

In duo-functional windows used in penal institutions, that is, where the muntin bars of the window function as glass supporting bars and as. detention bars, the closure 'for the Ventilating area may be assembled at the factory or on the grounds andvafter assembly mounted in position over the Ventilating areal with vthe glass panes already in position.y Likewise, the closure for l' standard commercial windowsvmay be glazed at the factory, at some central point or on the jobbefore mounting. This will hereinafter be referred to as field assembly. In field assembly windows, when the frame for the closure overlyl5 ing the Ventilating area is shipped from the factory without window panes, thev glass is inserted Y when the closures are on the ground. This permits of progressive operations by the employes. One mechanic, for example, may position the 7,0 frames on suitable racks. A succeeding mechanic may lay the glass. panes in position; va third may putty along one or more sides, ythere'being `as many mechanics as separate operations, in the eventthe job is'large enough. This has been ,25 found to greatly reduce the cost ofthe window assembly. e

After the closure frames have been glazed, the closure assembly is raised and placed in position over the Ventilating' area. This permits the use .30 of a Ventilating area in any selected place, inthe window. Any space or groupl of spaces left vacant for ventilation may be provided with a closure. It is not necessary that all of thewindows be uniform. v

Referring tothe drawings, the window assembly includes a plurality of horizontal muntin bars I0 and a plurality of transversely disposed vertical muntin bars I2 dividing the window into a plurality of spaces, some of which are glazed by window panes i4, leavinga pluralityof spaces vacant for Ventilating area, The muntin bars Al!) and I2 may extent across the YVentilating area to function as detention bars, or security bars, as the case may be. Y 45 In the modification disclosed, both the vertical and horizontal muntin bars constitute T-bars, havingthe flanges on the inside. Thus, the putty I 6 used in puttying the window panes of the fixed spaces is located on the outside of the window,` so as tobe out of reach of the inmates.' v It is very desirable to make a field assembly Vof the closure unit overlying the ventilating'area. By assembling the closure'unit on theground thecost of production is greatly reduced.l In

the embodiment best seen in Figs. 1, 2 and 3, the closure unit includes a fixed frame portion including a sill 2U and horizontal and vertical frame members 22. As may best be seen by referring to Figs. 2 and 3, the overhanging portion 24 of the sill is provided with one or more notches 26, one notch for each Vertical muntin bar passing through the Ventilating area. The overhanging portion provides drainage for water. The sill 20 carries a flexible or rigid retaining member 28, as the case may be, welded or otherwise secured to the under side of the sill 2i). The exible member 28 is provided with an angularly disposed portion 28a projecting towards the downwardly projecting sill portion 24. The angularly disposed portion 28a merges into a second deflected portion 28h. Portions 28a. and 28h cooperate with the overhanging lip portion 24 to form a channel 3B, adapted to slip over the upwardly projecting flange 32 of the muntin bar Il) bounding the bottom of the Ventilating area. In order to provide weather tightness a suitable mastic 34, or packing material, surrounds the upper flange 32 and lls the channel 3D.

The frame portion 22 is provided with a notch 36 supporting a sheet metal member 33 having a channel portion 4U adjacent to the flanges bounding three sides of the Ventilating area. The channel 4U is also filled with a mastic, or any other suitable pliable or yieldable material adjusting itself to the contour of the contacting surfaces, so as to seal the edges of the Ventilating area.

The muntin bars extending across the ventilating area function as detention bars in preventing the ingress and egress of human bodies through the window. In order to prevent the passing of small bodies, such as tools, implements, guns and the like, and in order to provide protection against insects, a screen 44 overlies the Ventilating area. 'Ihe frame 42 of the screen 44 is seated against the inwardly projecting portion of a sheet metal member 38. In addition thereto, the screen functions as a tell-tale, in that if it is mutilated or removed, it serves as a signal that an attempt at escaping through the Ventilating area is about to be made or an escape has beenvmade.

After the closure assembly has the channel 30 hooked over and interlocked with the upwardly extending flange 32, the closure assembly is bolted in position by a plurality of bolts or screws 50 passing through a washer 52 seated upon a retaining member 54, preferably provided with an arcuate portion overlying an arcuate flange 55 overlying a corner formed between the vertical and horizontal muntin bars. The flange 55 of the retaining member 54 is preferably provided with lugs 56, best seenlin Fig. `6. Lugs 56 are adapted to abut the frame of the closure to hold the parts in a more rigidl relation to each other.

'I'he screw 5B threadedly engages a suitable aperture 60 in a nut carried by the fixed closure frame 22. The head of the screw 50 is preferably made for use with a special tool, which prevents the removal ofthe screw 50 with an ordinary wrench or theV like. By tightening the screws 50 the frame 22 is securely held against the xed muntin bars bounding the Ventilating area. The mastic or sealing material 34 and the mastic or sealing material in the channel 40 seals the `boundary of the Ventilating area. This permits the entire closureassembly being assembled on the ground ioor oran'y other suitable place, where it is glazed -before being placed, von the xed window portion'. The retaining member 54 eliminates the use of holes being made in the muntin bar. Furthermore, it eliminates the use of lugs for holding the closure in position.

By this arrangement it is possible to leave any selected group of spaces vacant for a Ventilating area. After it has been decided upon what spaces are to be left vacant and the number of spaces, a suitable closure assembly may then be inserted, irrespective of the position of the spaces, without any alteration of the xed window portion. These spaces may be in the top of one window, in the bottom of another, or any intermediate location.. Likewise, a few spaces may be left vacant, or a great number of spaces may be left vacant. This arrangement permits a Very ilexible selection of Ventilating area, both as to Size and location, thereby permitting the production of standard parts at the factory, the standard parts being inserted in the eld, thus resulting in the reduction of the cost of production.

Furthermore, the screws 50 permit the removal of the closure assembly. Thereby this structure has flexibility, in that it is merely necessary to remove the screws 50 to move it to any other suitable location. In the event the Ventilating areas have been improperlyA located or it is necessary to meet changed conditions, the Ventilating area may be shifted to another portion of the same window by merely removing the necessaryv glazing, transferring the closure assembly to the newventilating area and glazing the unused old Ventilating area. Additional Ventilating areas may be provided by removing glazing from desirable glazed spaces and adding another closure assembly. Either shifting the old or adding new closure assemblies does not in any manner mar the appearance of the window assembly, as no holes, notches or recesses are required in the muntin bars and no parts are welded thereto.

The sill 20 and the frame 22 cooperate to support a pivotally mounted closure assembly including a sill portion '10, transversely disposed muntin bars 'I2 and Vhorizontal and Vertical members 14, cooperating to support the glazing 16. Again, the putty is placed on the outside of the closure so as to be o-ut of easy reach of the inmates. 'Ihe transversely disposed muntin bars 'I2 extending across the closure frame are of less width or thickness than the sill 'l0 and the frame member 74, so as to provide a pocket for the screen 42. The sill '1D is provided with a downwardly projecting flange 18 contacting a slanting surface of the sill 2U. In addition to the downwardly projecting flange 18, the sill 'I0 has another downwardly projecting lange engaging the inside of a downwardly projecting portion of the sill 2B, so as to provide a double contact arrangement, providing a dead air space 82 between the double contacts. The flange 18 terminates in spaced relation with respect to the bottom of the screen frame 42. Members 14 are provided with a pair of outwardly projecting flanges 9D and 92. These form a double contact with the frame member 22 leaving a dead air space 94. The flange 92 subtends or overlies the screen frame 42. In the modification disclosed in Fig. 4, a sill 10i) has been used. This sill is made from a piece of material bent into a loop, so as to provide a cavity 102 in the bottom thereof, forming a receptacle into which the inrushing weather is trapped, without blowing into the juncture formed with the downwardly projecting ilanges 18 and 80 of the sill of the movable closure. By properly designing this sill, a structure may be obtained wherein there will be no tendency for the weather to escape through the juncture btween the movable closure and the fixed sill portion. This structureis very eiiective as a safeguard against blowing rain.

In this modification the sill |89 supports a flexible member l iif'i cooperating with the downward# ly projecting iiange m6 to form a channel Hi8 into which the flange 32 projects. The sill I Il!) supports a pair oi vertically disposed frame members iiii and a transverse top member H2. Members il@ and H2 are provided with inwardly projecting flanges Ml providing an abutment for the frame members H6 of the movably mounted closure. A sheetV metal member H is mounted between the inwardly7 projecting flange Il@ oi members iii? and M2, and the flanges of the T-shaped muntin bars lli and i2. The sheet metal member H5 terminates in a channel H8 extending beyond the frame members lil and l I2 for supporting sealing material l Zii' contacting the outer edges or inner edges, as the case may be, of the flanges oi the muntin bars bounding the fixed portion of the window. The sealing material may be some initially plastic material or some yieldable material, such as felt.

The closure assembly is held in position by the screws or bolts 5l), holding the clamping member 5c against the flange of the muntin bar bounding the Ventilating area and engaging va suitable nut on the opposite side of the inwardly projecting ange i l in a manner similar to that disclosed in connection with the preferred embodiment shown in Fig. l.

In the modiiication disclosed by the fragmentary view shown in Fig. 5, the xed frame portion of the window includes ,an irregular shaped bar |353 bounding the Ventilating area and having attached thereto a closure assembly including the frame member |34 and the metallic member |32 extending in parallel relation thereto. Suitable bolts |35 hold members |32 and i3d in spaced relation to form the channel |38. The frame member |34 is provided with an inwardly projecting ange |36. Instead of utilizing a sheet metal member 3B or H5 for holding the sealing material, as disclosed in-Figs. l to 4, the sealing material is packed into the channel |38 formed between members |32 and E34. The movably mounted closure, including the frame Mie, is provided with an outwardly projecting iiange portion |152. contacting the edges of the ange portion |32 and the frame portion |34.

Although the preferred Amodification of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts which generally stated consist in a device capable of car.- rying out the objects set forth, in the novel parts, combination ci parts and mode of operatiornas disclosed and deiined in the appended claims.
